Question:

For <span class="math-inline">a > b > c > 0</span>, the distance between <span class="math-inline">(1, 1)</span> and the point of intersection of the lines <span class="math-inline">ax + by + c = 0</span> and <span class="math-inline">bx + ay + c = 0</span> is less than <span class="math-inline">\frac{2}{\sqrt{2}}</span>. Then
